Application filed March 31, 1931. Serial 1: 6. 526,694..

An object of the invention is to provide a valve and tappet silencer and clearance cushion which may be disposed between a valve stem and a valve plunger and which 6 acts as a cushion and which will also take up all slack between. the. valve plunger and the valve stem, whether the engine is cold or the parts have become warm or hot through the running of the engine. 1

Another object of the invention is to provide a silencer and cushion of the class described which has a casing in which is disposed a plurality of plates held spaced apart receiving an end of a valve stem being held at an end plate, and the other end plate being exposed for engagement by a valve plunger.

Additionalobjects of the invention will apthe preferred form of the invention is described.

In the drawing similar reference characters refer to similar parts in all the views, of which Figure 1 is a sectional view illustrating a valve with its stem and a valve plunger, with the silencer and cushion disposed in position,

Figure 2 is an enlarged sectional side view illustrating the construction of the silencer and cushion,

Figure 3 is a perspective view illustrating one of the spacing rings which are to be dis-. posed between the plates,

Figure 4 is a perspective view illustrating one of the plates, and

Figure 5 is a sectional view illustrating another form of plate having a spacing rim which may be used in place of the ring illustrated in Figure 3 and the plate illustrated in Figure 4 ofthe drawing.

By referring to the drawing it will be seen i 7 that the silencer and cushion A is used in connection with a valve having a stem 10 and r a valve plunger 11, the valve plunger 11 bemeshing with this threaded end 12, the nut being disposed for engaging an end of the silencer "and cushion. It will be understood that the invention relates to the silencer and at their peripheries, a disk with an orifice for pear in the following specification in which 111g provided with a threaded end 12, a nut 13 r a cushion and thatthevaIVe with its stem 10 and the valveplunger llwith its threaded end 12 andthe nut 13are merely illustrated to explain one use of the invention. The silencer and cushlon A has a casing 14,

thelower sides 15 of which are turned in-Y wardly to form a base having a central open ing 16 Disposedinthe casing14abovethe" v base there is a plurality of plates 17 which,

shown in Figure 2 of the drawing, are at their peripheries spaced apart by rings 18 so that the central portions of the plates 17 will be spaced from each-other. Above the plates 17 andtheir rings 18 there is disposed adisk 19, the disk 19 havingan opening 20 which extends through its opposite faces for 1 receiving the end 21 0f the valve stem 10. The upper sides of the casing 14 are bent inwardly at 22 to hold the disk 19 in close association with the plates 17.

When the silencer and cushion is used in connection with a valve stem and a valve plunger, as illustrated in Figure 1, the nut 13 on the threaded end 12 of the valve plunger 11 engages the lower plate 17 through the stem 10 is disposed in the opening 20 of the disk 19 and for engagement with the upper plate 17 within the casing 14.

It will be understood that the opening 20 in the disk 19 will be made of such a size as opening 16, while the terminal 21 of the valve to engage snugly the terminal 21 of the valve stem 10 and that, with the adjustment of the nut 13, the silencer and cushion will be held upwardly so that the terminal 21 of the I valve stem 10 will be disposed at the upper plate 17, which will enable the movement of the valve plunger 11 to operate the valve through its valve stem 10. When the enginebecomes heated, and the valve stem and the valve plunger expand, the disk 19 will take up this expansion and still provide a close coupling between the valve plunger and the valve stem. In this way, the valves will be prevented from rattling and an even movement of the valves will be obtained under all conditions and irrespective as to whether the engine is cold or has become heated.

In Figure5 there is shown a plate 23 which may be used in place of the plate 17, each of the plates 23 having a spacing rim 24 at its periphery, so that when the plate 23 is used, the spacing rims 24 will serve to hold the central portions of the plates 23 normally 5 away from each other to accomplish the result desired and which has been explained in connection with the use of the plate 17 and the spacing rings 18.

What is claimed is:

In an internal combustion engine, a thrust transmitting device for positioning between the thrust member and valve stem to compensate for relative movement therebetween caused by expansion and contraction of said valve stem and/or member, said device comprising a cylindrical casing of sheet material, at least four resilient, plates disposed within the casing in superimposed relation, a disk at one end of the casing and in superimposed relation with respect to said plates, said disk having an opening extending therethrough and receiving the valve stem therein, said valve stem freely contacting With-the outermost of said superimposed plates adjacent the said disc, the other. outermost plate freely receiving the thrust member thereagainst, means spacing'said plates from each other at the point where the thrust is exerted, and turned-in annular flanges at each end of the casing for holding the disk and plates together. v
